parcimonie binary package in Ubuntu Trusty i386

 parcimonie is a daemon that slowly refreshes a GnuPG public keyring
 from a keyserver.
 .
 Its refreshes one key at a time; between every key update, parcimonie
 sleeps a random amount of time, long enough for the previously used
 Tor circuit to expire.
 .
 This process is meant to make it hard for an attacker to correlate
 the multiple performed key update operations.
 .
 See the included design document to learn more about the threat
 and risk models parcimonie attempts to help coping with.
